Be it known-that We, W1LLIAM` JAMEs LANE, citizens' ofthe VPouo'hlice sie,v

LANE and GEORGE ,invented certainfnew and useful Improveam'entsgin Boilers and Attachments to be used in Connect-ion Therewith, of 'which the following 1s 'a'specificationl o a steam-boiler and its,attachments as 'designed for use upon a m'otorfcarriage.

(Dur Ainventionconsists first, in the `construction ofthe boiler, `which embodies the' characteristics 4ofl a vertical 'fire-tube boiler -and. ailash-boiler-j second, in an attachment designed Vto separate the steam,

the heated feedfwatergiand the solid matters from the Water'or-igir'lallyy fed to the Hash 'portion-of deliver the steam into the steamr-space, the.4 heated feed-Water into the the tubular portion of the boiler at the full temperature Aof the Water insuclrp'ortion of. the boiler, and to collect the solid matters--such asmud, scale, .&c.-in

a suitable" Vmud-drum l1 third, in an attachment designed to automatically control thel Waterle'vein the tubular p-ortion or'vr the boiler.

Vertical 'fire-tube boilers las heretofore conseruoted vhave been.l found -ob1ect1onable for the reason that'the large number and small sive fthelire-tubes' employed have acted to out down the" draft through Vthe boiler, and thus' prevent free development ofrlame in pro ductsv oi'combustion from the'burner under the boiler` upward through the t'ube's,

.the flame and products obtained, and, further; carrying the burner and rapidly. to cause the flame when a motor-car destroy the casing surrounding the boiler' and burner and .otherwlse injure the vehicle.

types ofboilerJ inthat the Vsteam used for or matters contained in the Water shall be separated therefrom before reaching 'thetubular portion of the boiler, and that dry steam shall be fedto the engine.

The .purpose ofthe automatic Water-level device is toinsure that th-i Water-level in the tubular portion ot lthe boiler shall .be maiutained at a lconstant level.

The accompanying'dravvings Will serve to illustrate our invention,i11Wh1ch--'l Figure 1 is a side elyationof aportion of a 'motor-car With the shell of the 'b .oilerbroken away at tWo places to show the relatin of the flash and tubular, portions ofthe' boiler supplemental steam ns'edfor heavy and that ofthe burner to the V tubular portion.

The upper portion of' the boiler is con-' structed in all respectsl like a lasli-boilerthat is, there is located in such portion a ,spirally-coiled tube '16. In the drawingsV the tube is illustrated as havingeight superposed layers, each of which is made of' three-eighths inch brass pipe. The size of .such tube and the dis )osition of the layerslinay be different from t iat stated without departing from the intent of'our invention.; All thatI is required is that such tube\shall be disposed in the pathway of t-he products of combustion from the burner after leaving the vertical fire-tubes of the boiler andbesufiiciently heated to convert a portion of the water passing through such tube into steam before the water and steam are 4delivered into the lower portion of the boiler. p "y w In order to carry the steam and heated feed-w ater derived from the flash portion of the boiler into the tubular port-ion of the boiler and to separate the steanrfrom the heated feed-water as well as the mud, scale,

`&c., there'is located on thc-'outside of the boiler a separating device, Whiel'. consists of the separating-drum 17 and mud-drum 1S. The interiorot the drum 17 is .connected to the delivery-orifice of the tube 16 through a .pipe 19,' which is somewhat larger in diameter and which pipe projects into `the side ci' the drum 1T, as shown in Fig. .3, and discharges the steam and heated feed-water from the tube 16 into the drum 1T in a tangential direction and at high velocity. The

impact of these bodies againstthe interior wall of the drum 17 nnparts to them a rotary motion, whereby the heated feed-water is the steam flows to the top of the drum.v The thrown against the inner -wfill ot' the drum and flows to the bottom oi' the drum.- whiie .or -p-recipitable metter-such as .lisehezfred into the steam-space oi' the tubuvlin' portion'ol" the boiler1 while the heated from whence sneh bodies maj.' readily be removed b\' taking oil' the lower heed ol' the drum. l

ln practlce we have found that some sop- -nnulieate arating device 'is necessary between thel flash portion of the boiler andthe t -bular portion of the boiler, as otherwise the-steam collected .in the steam-space of the tubular portion ot the boiler containsi so much Water as to seriously interfere with the action of the engine fed by such ste-am. The separating device which we have .described is 4the best of which We are aware. Ve, however, do not Wish to limit ourselves to the specific forni of separatingI device shown, as'other means for .separating the steam and heated feed-Water, as also the solid matters, may be employed. The feed-Water for the boiler is fed from water-tank 23 through pipe 24 to a pump, (indicated'at 25,) operated by engine 26., and is discharged through pipe 27 into a. coiledpipe heater 28, situated in a steam-space in the upper portion of a condenser 29, and lpasses thence by'pipe 3() into' the inlet-orifice' of the spirally-coiled tube 16. The feedwater-may also pass by pipeSl to automatic` water-regulator 32 and thence by pipev 33 pass around the pum.

The arrangement of the automatic regulater for controlling the by-pass and maintain ing,r thewater-level in the tubular portion 'of the boiler is best shown .in Figs. 2, 3, and 4 and consists of a T portion of pipe 34, made preferably of brass, plugged .at both ends, and ee-ured to the upper end of a pipe 35, which pipe is connected at. its lower end with 'the interior of' the boiler at the designed waterlevel. Surrouinlingr the T port-ion of pipe is aframe 36, Fig. 3, and pivoted in this frame opposite one end 'ot' the T portion is an arm 3T, carrying an adjusting-screw 38. The lower end of this arm-37, which is forked, surrounds the valve-stem 3Q of a valvechainher 10, with which the pipes 31 33 com- -This valve-stem 39 is pointed at the end and rits in a seat in thevalve-eham- 'ber and also moves through a suitable pack- 'ing-head.

interposed'between,the frame S5 and ahead 42 on the endof the stem is a heie-al spring' 43. which spring by its tension under nornml conditions serves to hold-the vaivestem in the position shown-that is, with the pipesfzll 33 in eon'nnu'iiieation through the valve-chamber -1-.(-). The purpose oit' the adjusting-nuts 3S and -H is to permit of regulation in accordance with the expansion of the T portion 34.' .The operation oi this portion of i the device will be readily understood.
